.rERooLA'roR- l ff Appiiatio mea August e, 19715.@ serial nbAaeisf To all 'whom z't may concern.' 'i Be it known that we, BENJAMIN Michigan, have invented a certain new and useful Percolator, of which the followingis a specification.

This invention'pertains to a percolator forV expeditiously preparing a small quantity of beverage, such as coffee, whereby a freshly prepared ycup or two of the beverage may be served by a restaurateur upon order a guest. v

lAccording to this invention, a small quany tity of ground cofee is deposited within a perforated container whichis' positioned within the 'percolator, the latter having a pouring tube the Vinlet to which is"`adja cent to the container, whereby water may flow through the coffee for extractiugv the essential oilstherefrom andthe resulting beverage is caused to again flow, in fa Vre'- verse direction, through the ground'coliee and thence to flow directly into the pouring spout, the liquid thus flowing and relowing throughthe ground coffee for effec-ting athorough extraction. i 1

A salient feature of the invention consists of means'for effecting a slow retarded flow of the liquid through the ground coffee,

whereby theV liquidl remains' in contact with the coffee for an appreciable length'of time and the retarded flow of the liquid prevents 'the finely ground coffee from beingwashed off the perforated metal so as to result in exposure of the bare mesh of said metal. To this end, awater receptacleis employed, the same having a depending'nipple'provided with a perforated bottom adapted to extend into the coffee container, saidwater receptacle extending over they nipple and being provided with apertures positionedl Figs. 2 'and 8 are horizontal sections rtaken on the linesQ-LEZ and 34-3 respectively of n Thepercolator'embodies la vessel 10', com 'posed of metal or othermaterial and con` struoted of' a desired shape and siz`e,y As shown, the vessel is open at the top, and is provided with a'suitabl'e handle 11. vessel is provided, also, with a pouring tube 12, the inlet towhich is at a point intermediate th'e height' of said vessel, said inlet to the tube being covered' by a perforated partition or ',screen'l.

'y Interiorly of the vessel, below the inlet to the' Vpouring spout, is a coffee container 14, the same comprising ra perforated bottom 15 attached'to a wall 16 and to the vessel Y Specification oflLetters Patent. -Patented0(i,t.i9,191r7,

Said

1(). lThe coffee container is shown in Figs.

ywithin ythe receptacle; but it 1 is apparent v that the particular shape of thereceptacle or fof itsbjottom may be modified as de sired. K Y

Removably fitted within the vessel 10 is a with a handle 18 for inserting or removing said receptacle. ,The bottom 19jof said receptacle is inclined, and 'at the lowesty part of the bottom is a ldepending nipple 20, the

water receptacle' 17, the same beingprovided latter being adapted to extend into the coffee container" 14.' The nipple '20 is provided with a perforated Abottom 21, composedof vwire'gauzeorperforated metal, and upon the assemblage of the water receptacle' with respect to vessel' j 10 and container 14 the perforated vbottom 21 is positioned with the nipple 20 withinthe container 14, see Fig. 1, whereby the perforated ,bottoms 15, 21,'cooperate in confining the ground coffee with- "in the container. f l

y The water receptacle is provided, also, with a partition 22, the same being in the lnature of a vfalse lbottom positioned for controlling the flow of water so that it will not pass too` rapidly to and through coffee, but

on the contrary will flow slowly to the coffee and remain in contact therewith for an appreciable length of time. As yshown the partition is inclined oppositely to the bottom 19 of the receptacle, said partition being inclined at a sharp anglev next to one wall or' the receptacle and at a less angle rearwardly toward the opposite wall. .The partition extends across the nipple 20 so that water cannot liow thereto directly from the chamber of the receptacle, but as shown the rear part of the partition joins with 'a vertically positioned wall 23, thelatter connecting the rear end of said inclined partif tion l22 with the inclined bottom 19. In said wall 23 are provided apertures 24 through which the water is adapted to llow in streams whereby the wall 23 and inclined members 19, 22 cooperate in retarding the flow of water to the coffee container.

rlhe receptacle 17 rests at one edg'eupon a ledge 25 provided within the vessel 10, vand at its forward edge saidy receptacle is supported by the 'c'oi'itainer 14.

In operation, the receptacle 17 is removed from the vessel, a charge oli' ground coffee is deposited within container 14, and receptacle 17 is replaced for the nipple 2O to enter the container, in which position the bottom 19 is inclined toward the container and an opening 26 in the fronty wall of the receptacle 17 is in register with the inlet to the pouring tube. Water is now poured into the receptacle, the flow or water being directed rearwardly by the partition 22 and being retarded by the wall 23 so that the water flows in small streams through openings 24 and over the inclined bottom 19 to 'and through the 'nipple 20, its perforated bottom 21 and the perforated bottom V1K5 of the container 14. The waterthus lpercolates slowly through the coffee confined within the container 'and between the perforated members 15, 21, as a result of Twhich 'the water is incontact with the coffee 'for an appreciable length of time and 4the -'essential 'oils are thus Jextracted from 'the ground coffee. The, extract is stored within ythe ichamber at the bottom of the vessel 10, vbut to pour 'olf the coffee the percolator 'is decante'd, with the result lthat the 'extract flows through the ground coilee, again taking vup essential oils and ilavors therefromt`he liquid extract yflov'ving out through the container 14, ynipple 20, opening 26, and spout v,12, and ,said liquidfextract being thoroughly ltered by the 'action thereon 'f the ground coeea'nd the ystrainers 15, 21, 13.

It Vis apparent that the percolator yissimnple i'n Aconstruction Land economicalfot 'manufacture. The parts can be Y'reacli'ly assembled :for use, and asreadily separated to perlmit the Vlinterior 'surfaces'of the various .parts ,to be readily and beweging emessa. `Practical experience with ythe Idevice has `si'tiui'ed within the'vessel below said spout,

a liquid receptacle Vfitted removably within said vessel for feeding liquid to said container, and means for retarding the flow ot liquid from said receptacle to said coutainer, said container beingpositioned intermediatethe pouring spout and the chainbervof said vessel and operating to secure, during the decanting operation, retlowot the beverage into contact with the material within 'said container prior to the outlow of said beverage through said pouring spout.

l2. A Vpercolator embodying a vessel providedivith a pouring spout, a container at'- ltached to said vessel and positioned below said pouring spout, and a removable liquul receptacle, said receptacle being provided `with means operating to direct the llow oi liquid in an irregular path to the `container and to retardthe flow of said liquid to the end Athat the liquid will lilow slowly ,to the container and will remain in contacty for an appreciable length of =time ywith :a charge vor material adapted to lbe placed within the container, said container being positioned intermediat'e the .peur-ing 4spout and the,

"chamber of said vessel and 'operating to secure, during the decantjing operatiomfa relow of the beverage into .contact withthe material within said container prior to the .outflo ol'sai'd beverage through said pourv ing spout. i
